Title: Process for producing antibiotic xk-33-f2
IPC: A61K35/74
Filed: 1971-12-30
Abstract: 1368153 Antibiotic XK-33-F 2  ABBOTT LABORATORIES and KYOWA HAKKO KOGYO CO Ltd 30 Dec 1971 [30 Dec 1970] 60838/71 Heading C2A The new antibiotic XK-33-F 2 , a white basic powder having no distinct melting point but turning brown and decomposing at 205-210‹ C.; its hydrochloride salt containing C = 33À28%, H=5À51%, N=21-73%, the balance being oxygen and chlorine, the antibiotic being further characterized by an ultra-violet spectrum as shown in Fig. 1 with maximum absorption in neutral and acidic solution at 268 mÁ and in alkaline solution at 283 mÁ; an infra-red spectrum as shown in Fig. 2 having absorption peaks at 945, 985, 1050, 1160, 1230, 1330, 1500, 1670 and 3300 cm.<SP>-1</SP>; being soluble in water, slightly soluble in methanol and insoluble in other organic liquids (e.g. ether, ethanol, CHCl 3 , acetone, hexane, benzene, ethyl acetate and butanol); and being positive in ninhydrin and Sakaguchi's reaction, giving a yellow colour with KMnO 4 , and a negative reaction to Fehling's, Molisch's and anthrone tests; is produced by aerobically cultivating Streptomyces olivoreticuli var. cellulophilus in nutrient medium until the said antibiotic is accumulated in the medium and then isolating the antibiotic therefrom. The antibiotic is isolated from the culture by filtering off the mycelium and bringing the filtrate to pH 8 and absorbing on a weakly acidic cation exchange resin. An initial elution with 0À5N NH 4 OH gives a co-produced antibiotic XK-33-F 1 , an antibiotic similar to destomycin A; subsequent elution with 0À5N HCl yields a solution containing the desired XK-33-F 2  in the first fraction and another co-produced antibiotic XK-33-F 3 , said to be identical to Viomycin, on the later fraction. This first fraction is purified by absorption on active carbon and elution with 0À5N HCl/80% MeOH, followed by adsorption of the eluate on anion exchange resin. Elution with water gives a solution of XK-33-F 2  which is freeze dried and then purified by dissolving in methanol followed by precipitation by adding acetone.

Title: Wire stranding machine
IPC: D07B7/02
Filed: 1971-12-31
Abstract: 1378775 Stranding machines; unwinding tension control HAMANA IRON WORKS CO Ltd 31 Dec 1971 [25 June 1971 19 Oct 1971] 61071/71 Headings D1J and D1T A stranding machine (Fig. - 3) comprises a drive shaft 15 and a plurality of units in series, each consisting of a stationary body 19 (Fig. 1), a cylinder 5 rotatable therein and carrying a gear 7 engaging a gear 17 on the drive shaft, a pair of members 8a, 8b secured to the cylinder 5 and a cradle 3b for a wire supply' bobbin. 1b mounted on a shaft 12 in bearings 13, 14 mounted in the cylinder 5 or member 8b. Each wiretravels along the machine in a wave-like path, passing near the centre of the cylinder 5, and thus enabling the use of small diameter bearings 6a, 6b supporting the cylinder, which may be of. light aluminium alloy, and allowing high rotation speeds. Each cradle being mounted on an individual support and unconnected to the next support, a single unit may be readily removed or replaced. Lubrication of bearings 6a, 6b and gear 7 (Fig. 6) is by a pair of nozzle openings 22a, 22b from a passage 20 to which oil is supplied under pressure.  In the event of wire breakage or loss of tension, the faulty wire will move out of its normal straight path to the guide plate 106 (Fig. 5), and assume a curved path g, making electrical contact between a ring 107 and the earthed wire, and thus stopping the drive motor. A wire 2 (Fig. 8A) withdrawn from a bobbin 1 passes round a pulley 309 on a spring-biassed arm 302, and then round a fixed pulley 310. A braided brake-band 311 is attached to the arm 302 at 315, its other end being fixed at 312. An increase in tension of the wire moves arm 302, reducing the restraint imposed by the brake on the bobbin. Spring 307, biassing the arm, may be adjusted by attaching- one of its ends in any of a number of holes 308. The brake band tension is similarly adjustable at 315, and has a fine adjustment screw 313.

Title: Coin packaging machine
IPC: G07D9/06
Filed: 1978-09-22
Abstract: In a coin packaging machine having a detector which can sense misalignment of coins stacked in a cylinder, a control arrangement is provided which temporarily inhibits the packaging operation upon detection of misaligned coins but which automatically restarts the packaging operation if the misalignment is corrected, e.g. by vibration, before the elapse of a predetermined time. A cam shaft which controls the packing operation of the machine is caused to turn in reverse if misalignment is detected. The detector continues to sense for misalignment and if misalignment is eliminated during the rotation of the shaft in reverse, the cam shaft is caused to return to forward rotation to continue the packing operation, and if the misalignment is not eliminated, and the cam shaft has reached a certain predetermined position packing operations of the machine are ceased.

Title: Improvements in or relating to the cleaning of a conveyor belt
IPC: B65G45/18
Filed: 1980-11-20
Abstract: A method of and apparatus for cleaning a conveyor belt. A roller (10) is frictionally engaged with a downwardly facing load carrying surface of the belt (34) so that it is caused to rotate by the moving belt. The rotary movement of the roller is transferred via a gear train (14, 20) to a brush (16) which is upstream of the roller and in contact with the belt. The belt is brushed by the brush in a direction which is opposite to its direction of movement and thus material brushed from the belt is directed downwardly and away from the roller. A substantially constant force is continuously exerted on the brush, which is movable more or less perpendicularly to the belt surface, so that a constant brushing force is maintained as the brush wears in use. <IMAGE>

Title: Bezel and crystal assembly
IPC: G01D11/26
Filed: 1981-10-01
Abstract: A transparent crystal 4 of thermoplastic material is received in the central opening in a watchcase or bezel 2 and includes a rear wall 4c supported on an annular shoulder 2d of the case, and a side wall 4d adjacent the case wall 2a which defines the case opening and which also defines an annular groove 2c extending into the case. The crystal 4 also includes a front wall 4a having a narrow band of material around its periphery which is thermoplastically worked by means of a heated tool 6 and deformed toward the supported rear wall 4c to form in situ a narrow annular trough 4e in the front wall and a flange 4f on the side wall extending into the groove 2c in the case to stake the crystal 4 and case 2 together and reduce infiltration of foreign matter into the case. A dust and water-resistant case/crystal assembly can be made by interposing a sealing gasket (not shown) between the case and crystal such that the gasket is compressed during thermoplastic writing and maintained in the compressed condition by staking of the flange of the crystal into the case groove. During heating and deformation of the narrow band of material on the front wall of the crystal, the case wall 2a in effect functions as a mould surface for the thermoplastic working step, and the shoulder 2d provides support against unwanted deformation of the crystal. <IMAGE>
